Halfway Between 45 and 218

When you ask "What number is halfway between 45 and 218?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=218.

Halfway Between Line

To find the number halfway between 45 and 218, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 218 into our formula, we get:

(45 + 218)/2 = 131.5

Thus, the number halfway between 45 and 218 is 131.5.

To check that our answer is correct, we subtract 45 from 131.5 and subtract 131.5 from 218 and compare the two numbers:

131.5 - 45 = 86.5
218 - 131.5 = 86.5

As you can see, the halfway number is 86.5 higher than 45 and 86.5 lower than 218. Therefore, our halfway between answer of 131.5 above is correct.
